Ultra-High Efficiency Gas Turbine (UHEGT) with Stator Internal Combustion

摘要

Provided is an internal combustion system for an ultra-high efficiency gas turbine (UHEGT) engine which includes a fuel injection system, an ignition system, a stator system, and a rotor system. The stator system includes a plurality of stators positioned radially around a central axis. The fuel injection system injects fuel within the stator system and the ignition system is located within the stator system allowing combustion to take place therein. The rotor system includes a plurality of rotors positioned radially around the central axis downstream from the stator system. The UHEGT-technology completely eliminates the combustion chambers and replaces the latter with a distributed combustion system using stator-internal combustion technology. This technology allows for an increase in the thermal efficiency of gas turbines of at least about 7% (and in many cases much more) above the thermal efficiency of the most advanced existing gas turbines.

1. A stator-internal combustion system for an ultra-high efficiency gas turbine engine comprising a fuel injection system, an ignition system, a stator system, and a rotor system,
wherein the stator system comprises a plurality of stators positioned radially around a central axis and wherein the stator system has a leading edge and a trailing edge, wherein the fuel injection system injects fuel within the stator system through at least one of the following mechanisms: a) a plurality of conduits which inject fuel at the leading edge of the stator system and b) a plurality of conduits which inject fuel within the stators themselves; wherein the ignition system is located within the stator system, wherein the rotor system comprises a plurality of rotors positioned radially around the central axis downstream from the stator system; and, wherein the stator-internal combustion system does not require the use of a gas turbine combustor.
